Source: Chip Learning Original Author: Chip Future The CH201 is a miniature, ultra-low power, long-range ultrasonic Time-of-Flight (ToF) distance sensor. Based on Chirp’s patented MEMS technology, the CH201 is a packaging system that integrates a PMUT (Piezoelectric Micro-Machined Ultrasonic Transducer) and an ultra-low power SoC (System on Chip), allowing the SoC to run Chirp’s advanced … Read more
Recently, I have been learning STM32 to create a simple application, and I thought I would share an article. The microcontroller used in this article is the STM32F103C8T6, the ultrasonic distance measuring module is the HC-SR04, and the distance results are displayed using a 0.96-inch OLED screen module. Effect Display The display result when the … Read more
